To all, The Public Comment session of City Council where we will discuss the LED lighting has been moved to January 6th at 9:30 am. If you wish to speak, write citysecretary@houstontx.gov or call 832-393-1100. Speakers are limited to 3 minutes. For your information, I just received a list of cities installing warm LEDs instead of cooler ones. These truly are the new improved LED street lights and we intend to support that point. This just came in from Chris Monrad, a lighting consultant for the International Dark-Sky Association who says that the efficiency of warm LEDs are now within a few percent of white LEDs: New 3000K LED street lighting and parking garage fixtures hitting the market with latest LED chipsets in 4Q/2015 1Q/2016 are only 4% to 7% less efficient than 4000K chips per GE, Hubbell, and Acuity Brands. This value is well within the margin of error for any street lighting calculations or models. Tucson AZ: 3000K Lake Worth FL: 2700K Davis CA: 2700K Cambridge MA: 3000K Gloucester MA 3000K Sahuarita AZ : 3000K Oceanside CA: 3000K Tucson Intl Airport: 3000K Colonel Smith Middle School , Fort Huachuca AZ: 3000K with only overnight Amber LED arrays operating Walden Grove High School Park Sahuarita AZ 3000K with only overnight Amber LED arrays operating Los Angeles - 4000K initial city-wide spec, 3000K now being used for later residential modernizations Western Riverside County (in programming) 2700K Residential, 3000K Commercial Honolulu 4000K originally specified; project put on hold, with new 3000K spec likely Phoenix 4000K originally specified; project put on hold, with new 3000K spec likely In addition, Calgary is also selecting warm LED street lights for residential areas. They are showing concern for the well being of their citizens.
